How to Control Oriental Cockroaches

Despite their name stating otherwise, the Oriental Cockroach didn’t actually originate from Asia. Entomologists believe that this cockroach is native to North Africa. Through travel and trade it has made it’s way to the USA and primarily is found in the Northern United States. Unlike most cockroach species which like to live close to human dwellings where they can easily gain access to food and water, the Oriental cockroach prefers to live outdoors. In fact, it thrives in the natural environment. However, in the north, the Oriental cockroach is slowly adapting to enjoy our indoor perks, making it a pest homeowners have to deal with.

Oriental cockroaches have smooth and shiny black bodies and are about 1.25 inches long making them one of the larger kinds of roaches. They have wings, but they are mainly there for show as neither male nor female roaches fly. Female oriental roaches are larger than male roaches, spanning about 1 ¼" compared to 1" for the male.

The oriental cockroaches prefer an outdoor habitat where they feast on decayed organic matter in mulch piles and rubbish. They also enjoy starchy foods. They are surprisingly able to withstand freezing temperature outdoors for long periods of time compared to other roaches who like warmer climates. They usually enter human homes when they are in search of water to fulfill their need to be around moisture.

Oriental cockroaches often enter structures through door thresholds, under sliding glass doors, along utility pipes and through floor drains. You may be able to detect them from their unpleasant and strong odor. If you have these roaches living amongst you, Solutions Pest and Lawn has everything you need to get rid of them.

How to Get Rid of Oriental Cockroaches: 4 Step Solution

Oriental Cockroach control doesn’t have to be difficult. With the right control approach and high-quality products directed towards cockroach elimination, you can be cockroach-free. Oriental cockroaches require persistence, patience and the right techniques in place for maximum success. We have laid out an easy to follow series of steps below which if you carry out accordingly, will kill any roaches you have in your home and keep roaches that are outdoors from coming in.

Step One: To start, it is important to keep a clean house free of food scraps that oriental roaches can scoop up and in particular water sources it can enjoy. Oriental roaches prefer cool and damp places to build nests and hang around so be sure to give your home a good inspection to see where they likely are hanging around. These roaches are often found near water sources like toilets and sinks. Make sure your plumbing pipes are tight and are not dripping or leaking and keep your home as dry as possible.


Step Two:
 Another non-chemical method of control you can put into place before breaking out the treatment products is exclusion measures that will keep oriental cockroaches out of your home. Use a caulking gun to seal off as many possible points of entries into your home. This will prevent roaches from gaining easy access into your home. Outdoors make sure to clear debris and address any damp areas or places with standing water. What you are trying to do during this phase is make your home less appealing to roaches.


Step Three:
 Once you've taken preventive measures both outside and inside you can then move on to treatment options. We suggest using a combination of baits, sprays and dusts so if roaches are resistant to one method, they will succumb to a different method of control. Baits like Apex Gel Bait or Ficam Insect bait work best indoors because of it’s delayed reaction and maximum impact of wiping out entire infestation which share the bait amongst one another. Using insect growth regulators like Gentrol Point Source is also wise to use to eliminate any eggs that have yet to be hatched on your property. Make sure to place roach baits in likely spots where roaches are likely to travel as close to nesting locations as possible. Use Fipro Foaming Aerosol indoors as a crack and crevice treatment and D-Fense Dust under appliances.


Step Four:
 Once the Oriental roach population has been eliminated, you should work to discourage those flying pests from returning through preventative measures. Regularly inspect your home for roach activity and maintain a regular cleaning routine (daily, weekly and monthly) to make sure the place is properly sanitized and unwelcoming to roaches.  Spray the exterior perimeter of the house with an insecticide like Reclaim IT to create a barrier that keeps roaches out. We also recommend using granules and spreading them across your yard as these roaches like to hang around outdoors.

 

LEARN MORE ABOUT ORIENTAL COCKROACHES

 

The Oriental Cockroach (Blatta Orientalis Linnaeus) is typically about 1 inch long with females being longer, about 1 ¼ inch long. Although this species of roaches have wings they can not fly. The wings in the males are longer covering their body, while the female’s wings are short and stubby. Because of their dark color and shiny exterior they are often confused with dark beetles. They are generally slower than other species and have the tendency to congregate around plumbing.

 

Habitat

 

They are often found outdoors in areas that provide them with warmth and moisture, such as leaves, stones, and piles of wood. They can also be found in shrubs, and flower beds, garbage,  and trash dumps. Indoors, this species of roaches are more of a cause for concern for homeowners for their preference for dark moist, and damp areas. Which often times means drains, sewers, and utility pipes. Because they often travel through structures through the plumbing and drainage they are more likely to come in contact with decomposing material, that includes feces, raw sewage, and general filth.

 

They been known to move indoors when the climate drops or if there are droughts and more commonly found in cool temperature regions.

 

Diet

 

It seems this species of roaches have a high preference for garbage and decomposing material, but like all its cockroach brothers, anything put in front of it can become a meal especially starchy materials.

 

Health Hazards

 

Because of their high preference for garbage, sewage, and decomposing material, and due to their living and travel preferences that include sewers, drains, plumbing, these species especially has a higher chance of coming in contact with dangerous bacterial parasites that humans wouldn’t normally come in contact with.

 

With their nightly foraging activity, these bacteria are then passed on to food serving surfaces and food supplies. In their bodies, one can often find bacteria, protozoa, and viruses. Like most cockroaches, they have been known to cause food poisoning, dysentery, and diarrhea and might be able to transfer E.Coli, Salmonella and other pathogens to food goods.

 

Life Cycle of Oriental Cockroaches

 

LIke almost all cockroaches the Oriental Cockroach has three developmental stages: The Egg Stage, the Nymph Stage, and the Adult Stage.

 

The Egg Stage: The life of the oriental cockroaches begins with the egg stage. The egg stage begins when the female cockroach carries the egg case for 30 hours and then deposited the egg case in a secured location.

 

Each egg case will be comprised of 16 eggs, and about 14 nymphs will emerge from each egg after 6 to 8 weeks have passed, or about 60 days later. The egg cases are about a ⅜ inch long and shaped like a purse.

 

The Nymph Stage: The nymph stage begins when the egg cases hatch and the nymphs emerge. They will go thru approximately 7 to 10 molts before maturing into adults, which can take about a year depending on climate. Before their first molt, they are light brown and ultimately turn darker by their last instar.

 

The Adult Stage: After going through their last molt the Adult oriental cockroach will be approximately 1 inch long and will be black or dark brown colored. They can generally live up to a year at the most. Males will have wings while females will not, but they will both be unable to fly.

 

The life cycle of Oriental Cockroaches from egg phase to their natural death takes about 86 weeks or 605 days. Oriental Adult cockroaches can live from 34 to 180 days, with the females being able to give birth to 200 new oriental cockroaches. Their development is seasonal and most adult cockroaches appear in early summer or late spring.

 

ORIENTAL COCKROACHES: COMMONLY ASKED QUESTIONS

 

What Causes Oriental Cockroaches?

High moisture levels like plumbing leaks, both summer and winter, and periods of Drought have been known to cause Oriental cockroach infestations.

 

One reason that could cause an Oriental cockroach infestation is the weather. During the summer and late spring, their development into adults finishes and they will more be active outdoors and might even venture inside your home foraging for food. When temperatures drop this species of cockroaches will often seek shelter indoors too, but it should be pointed out that they are capable of withstanding colder temperatures.

 

Another reason that could cause an Oriental cockroach infestation is periods of drought. During droughts mass migrations of cockroaches have been known to occur, as they depend on moisture to survive, the outside world will become inhospitable and the moisture created indoors through plumbing, air conditioner leakage, and the daily use of water in homes might attract them.

 

As they are primarily found in dark, moist, and damp spaces, having a basement, crawl space, and dark rooms in your property will give their the perfect location to set up shop, especially if there is a leak that has gone unnoticed. Making sure moisture levels in rooms that are dark, or damp, are low through either central heating or proper ventilation might discourage these pests from intruding.

 

Can Oriental Cockroaches Climb Walls?

They can not. They lack the adhesive pads on their feet that allow other cockroaches to easily travel up vertical surfaces.

 

Unlike other species of cockroaches, Oriental cockroaches are limited, in the sense that they are flightless and do not possess the sticky pads needed to climb up smooth vertical walls or surfaces. This is one of the reasons why most of their activity is often observed below ground levels, in basement and crawl spaces and even under sidewalks.

 

Where do Oriental Cockroaches Nest in Your Home?

In dark, moist, and humid places in your house. Also in drains and plumbing. They might even travel from the outside to forage indoors.

 

You can find this type of cockroach in dark, humid, and moist places that are usually below ground level. Indoors these place can include dark basements with high moisture levels, plumbing, drains, sewers, close to sinks and bathrooms, around the soil of the foundation of your structure and poorly lit areas that provide a suitable environment to nest.

 

Because these cockroaches mostly live outdoors close to garbage cans, underneath sidewalks, in sewers, under mulch, near natural debris that provide suitable moisture, they might be nesting outside your home, and are traveling inside your drainage and plumbing systems which has been known to occur.

 

Do Oriental Cockroaches Bite?

Oriental Cockroaches have not been known to bite people, but they still might be able to.

 

Out of all the cockroaches, only the American cockroach and Australians cockroaches have been documented to bite people, and these cases have been very rare. Could these cockroaches bite people, maybe, but you should be more concerned with the disease and bacteria that they are capable of spreading throughout your home, which could prove many times more dangerous than a simple bite.

 

Are Oriental Cockroaches Harmful?

Yes, due to their preference for garbage and decomposing material they are more likely to have pass bacteria and viruses through their foraging.

 

These species of roaches are more prone to travel through plumbing and drainage, and due to their preference of decomposing material, they are more likely to come in contact with dangerous bacteria, harmful pathogens, and viruses.

 

Although all cockroaches are capable of transferring diseases and viruses, the oriental cockroaches have a higher chance of transferring them due to their travel preferences which will often occur inside drains and plumbing that are riddled with bacteria.

 

How Big Are Oriental Cockroaches?

They are about 1 to ¼ inch long.

 

These cockroaches are usually about 1 to 1 ¼ inch long, with the females being 1 ¼ and the males being about 1 inch long, both sexes are dark brown or black in appearance. The males have wings, unlike the females, but both sexes are incapable of flying.
